I have tri-axial data from an accelerometer, however, I know in retrospect that it was not aligned properly when placed on a mechanical arm. I know because when looking at the values at stationary ins …

It measures acceleration in terms of $g$. I have read some literature but I am unsure about the alignment issues involved. …

I have a problem deriving displacement from an accelerometer; I want a time series of displacement so I used numerical integration twice; I based my code on the trapezium rule and so did something li …

I was wondering if anyone could shed some light on this problem. I have placed two accelerometers on an animal one sampling at 50 Hz the other at 100 Hz. They were placed in the same position. I then …

And then I was thinking that the displacement in the x and y direction would be $$ x(t) = r \cos(ω t) = r \cos(2 π f t) $$ $$ y(t) = r \sin(ω t) = r \sin(2 π f t) $$ and so acceleration …

Am I right in thinking that I would expect the acceleration in z to be 1g? … Then in the x and y plane I would expect a read out of acceleration in $X(t) = -2\pi fr\cos{(2\pi f t)}$ and acceleration in $Y(t) = -2\pi fr\sin{(2\pi f t)}$ where $r$ is the radius of the wheel and $ …
